Ventilation is the introduction of outside air into a space. Under normal operations, most HVAC systems recirculate some air to save energy. The system will mix in some outdoor air based on the code requirements for the space type and its designed occupancy. A typical ventilation rate is 15 cubic feet per minute of outdoor air, per person.Both the outdoor air and the recirculated indoor air are filtered by the HVAC system before being supplied to the occupied spaces.
During the pandemic, Cal OSHA guidelines have required the campus to “maximize ventilation and filtration” as much as possible.
KOKA-TECH HVAC INC has done this by changing the buildings to 100% outside air, meaning with no recirculation, in all buildings in which the system can perform this way. In the very few buildings which require some recirculation, the amount of outside air has been maximized as close as possible to 100%. Some campus buildings do not have mechanical ventilation at all. In most cases, these buildings have operable windows which can be used to provide air flow.
